Wladimir Klitschko and Mariusz Wach are both fit and ready for Saturday night's heavyweight championship battle at the O2 Arena in Hamburg, Germany.

Klitschko (58-3, 50KO) weighed in at 246.9 lb (112 kg), notably lighter than the career-heavy 249 lb he posted for his 6th round stoppage win over Tony Thompson in his most recent appearance in July. Wach (27-0, 15KO) came in at 249.1 lb (113 kg) for his first-ever crack at a world title. The 6***8242; 7½***8243; challenger is the first opponent to have a height advantage over the 6'6" Klitschko, as well as boasting a slightly longer reach.

The heavyweight championship marks sixth defense of the lineal crown for Klitschko. On the alphabet side, it's the 12th defense of the belt he acquired in his April '06 rematch with Chris Byrd to start his second title reign. [Click Here To Read More]
